I just noticed today that a local station i fill at has an e30 pump. Now I'm considering an e30 tune but can't find any info on 3.5eb flex fuels. My cap says e15 max but that's just software and programming reasons right? The pumps and lines and injectors and whatnot are ethanol safe on all these newer vehicles right? There aren't any flex fuel e85 3.5eb are there? Everyone running these e30 tunes must be doing it in a non flex fuel EcoBoost? And tuned there won't be any check engine lights or anything? Anyone else running e30 tunes?
